EGG OPENER Filed Jan. 16, 1929 FIE E [NVENTOR flar/d /7. Jonas A TTORNE YS Patented June 24, 1930 UNITED STATES PATENT OFFICE DAVID E. JONEBQOF SODA BIRINfiS, CALIFORNIA EGG ORIENTED I 7 Application filed January 18, 1999. Serial No. 838.890.

The device of my invention relates to a means for opening eg s and similar articles, One of the principal o iects of the invention is to rovide a device of this character which i, is e active to o on and separate the respec= tive portions an egg.

Another object oi t llS invention is to pro vide an eiiective egg opening device of simple, inexpensive but rugged structure, sanitary so and reliable in operation.

A further ob ect of this invention is to provide a device which is easily operated to eilipiently open eggs.

The invention possesses other advantageous it features, some oi which with the loregoing, will be set forth ct lcngth in the following de scriptioni, where I shall outline in full that form of my invention which I selected for illustration in the drawing accompanying and forming cart oi the present specification. In said drawing, I have shown one type of egg opener embodying 1n invention but it is to be understood that N do not limit myself to such ty 'e, since the invention, as set forth in the c aims,-1nay be embodied in a plurality of forms.

In the drawings:

Figure 1 is a plan view of the device of invention.

igure 2 is a plan view of the device of my invention showing the sections oi the egg receptacle in open position.

Figure 3 is a section through the device of my invention along the line 3--3 of Figure 1.

Figure l is an end. view of the device of my invention which is shown sectionally in F1 are 3.

' f igure 5 is a plan view of the under side handle provide means for receiving and of my invention with the bottom cover plate holdin an egg which, expeditiously, is forms of the two so arable, ellipsoidal receptacles 8 and 9. hose receptacles are pivotally mounted on the handle 6 by means of the pins 11 and 12.

The receptacles 8 and 9 are each provided preferably with rectangularly shaped'extenclone 18 and 1% which, as shown more particularly in Figures 2, 8 and 4:, are adapted to receive thereon egg cutting linivosclo. As

shown in Figure 4 each knife, which is praierably formed with several char projecting teeth 17,. is provided, preferab y, with the several grooved portions 18. T ese render the knife movable on the rectangularextension of the receptacle and yetretain it in position. The several groove ortions 18 are conveniently formed by hen ing over portions oi the knife. f

To actuate the knives for the cutting at an egg shell means are conveniently rovided in the wire loop 21 which is suitab y placed in operative contactwith each kniie. Thus I provide a hole 22 in each knife and a slot 93 in each of the receptacle extensions thru which the loo is assed. Movement of the loop, within t e limits permitted by the cattensions, moves the knives into or out of the ppripheral portion of the egg receptacle.

ovement o the loop is accom lished, usual- 1y, b havin the ends thereof isposedwitb in t c han e dand the extreme and por gl tions suitably formed to be received by some 4 'means of actuation. bent over and received within the rooves 55 Thus the ends 26 are 27 in the plate 28 which is likewise isposed within the handle. I usually form thetri ger 29-integral1y with the plate 28 to simpli y the structure.

As means for returning the egg opening device from its extreme open osition, as will be later disclosed, I prefers 1 provide a spying 88 suitably attached to t c handle by a pin 34: and to a bent portion 36, of the actuator p1ate28. To retain the various operating 'mcchanisms in their proper rclationshi s within the handle, and for other reasons, provide the bottom cover plate 37, shown in; Figure 0, whichis' suitably adopted to be retained in its desired position upon the handle.

the cutting travel of the knives I To separate the egg after it has been cut I usually provide the loop 41 the ends 42 of which are pivota'lly retained in the respective portions of the egg receptacle by means of the holes 43. These are so disposed that movement of the loop will cause the portions of the egg receptacle to move pivotally on the handle. To move the loop I conveniently provide that the bent portion 36 of the trigger structure shall be sufficiently long and so positioned with respect to the loop that it will engage the loop when the cutting knives have completed their cutting operation.

In operating the opener, an egg is placed in the egg receptacle which normally has the position shown in Figure 1. Depression of the trigger first moves the knives into the peripheral portion of the receptacle and so into the egg. It has been my experience that with the device of my invention, which has been described in its preferred form, the egg is not shattered, as is usual with other devices of this character, but-is generally neatly severed across substantially the minor axis of the egg. This facilitates the discharge of the egg contents from the egg shell free from any broken pieces thereof and also expedites the removal of the severed shell from the device. Continued depression of the trigger causes the ends of the loop to travel outwardly in the grooves in the bottom plate thus disengaging the loop from the actuating plate and discontinuing the cutting travel of the knives. At this point the bent portion of the trigger engages the receptacle separating loop and, upon further depression the portions of the receptacle, together with their respective knife blades, are separated-as shown in Figure 2thus materially opening the egg and allowing the discharge of its contents.

The portions of the egg shell are then removed; the release of the pressure upon the trigger allows the spring to exert its force and return the several mechanisms to their normal positions. Thus the actuator plate 28 is returned to its normal position and, in so returning, the shoulders 44 formed upon the plate engage the loop ends, which are in the outer portion of the grooves 38, and cause their return from their inactive position to positive engagement with the grooves 27 in the plate 28. The pressure on the loop &1 is also released, the receptacles 8 and 9 returning to their normal closed position, as

shown in Figure 1. The broken portions of tions being pivotally mounted on said handle,

egg cutting knives cooperatively mounted on said sectional receptacles, a trigger mounted on said handle, a lip formed at one end of said trigger, a wire loop cooperatively attached to said trigger and to said knives, said handle having outwardly extending grooves wherein portions of said wire loop are passable to remove said loop from cooperative contact with said tri ger, a second wire loop eccentrically positioned with respect to said sectional receptacle said second loop being engaged by said trigger lip upon depression of said trigger to move said receptacles pivotally, and a spring attached to said handle and to said trigger lip.

2. An egg opener comprising a handle, a trigger on said handle, an egg receptacle divided into sections, said sections being pivotally mounted on said handle, a knife on each of said sections, a wire loop connected to said knives and to said handle, said loop being adapted to be engaged by said trigger and to move said knives into the peripheral portions of said sections upon actuation of said trigger, means on said handle for disengaging said loop from said trigger, a second wire loop connected to said sections and overlying said handle, said loop being adapted to be engaged by said trigger upon my hand.
